Question

所以我希望有一个显示cookie的响应式页面。我希望函数的值在输入值内的页面加载时显示，但我只能使用onclick函数显示它。这是我的代码：

<script type="text/javascript">

     function readCookie(FullName) {
       var name = FullName + "=";
       var ca = document.cookie.split(';');
       for(var i=0; i<ca.length; i++) {
         var c = ca[i];
         while (c.charAt(0)==' ') c = c.substring(1);
         if (c.indexOf(name) == 0) return c.substring(name.length, c.length);
       }
       return "";
     }

</script>

<label>First Name from cookie: <input id="name2" maxlength="25" name="namefield" readonly="readonly" size="20" type="text" /> </label> 

<input onclick="document.getElementById('name2').value = readCookie('FullName')" type="submit" value="Get cookie" />

如何在不使用提交按钮的情况下让函数在输入中显示结果？

在<script>之后使用提交按钮<input>属性的内容制作一个onclick元素：

<script type="text/javascript">

     function readCookie(FullName) {
       var name = FullName + "=";
       var ca = document.cookie.split(';');
       for(var i=0; i<ca.length; i++) {
         var c = ca[i];
         while (c.charAt(0)==' ') c = c.substring(1);
         if (c.indexOf(name) == 0) return c.substring(name.length, c.length);
       }
       return "";
     }

</script>

<label>First Name from cookie: <input id="name2" maxlength="25" name="namefield" readonly="readonly" size="20" type="text" /> </label> 

<script>
  document.getElementById('name2').value = readCookie('FullName')
</script>

我想使用jquery在输入中显示特定的cookie
